  • CRISPR/CAS EFFECTOR PROTEIN AND SYSTEM
    Publication number: 20260159821
    Abstract: The present invention relates to the technical field of clustered regularly interspaced short palindromic repeats (CRISPR). In particular, the present invention relates to a Type I-A CRISPR-Cas effector protein and system, a fusion protein comprising the protein, and nucleic acid molecules encoding same. The present invention also relates to a complex and composition for nucleic acid editing (e.g., gene or genome editing, large fragment deletion, single base editing, genomic structural variation), which comprises the protein or fusion protein of the present invention, or nucleic acid molecules encoding same. The present invention further relates to a method for nucleic acid editing (e.g., gene or genome editing, large fragment deletion, single base editing, genomic structural variation), which uses the protein or fusion protein comprised in the present invention.
